Wanted:WANTED! AMD AM2+ x2 2GB MOBO CPU RAM combo, PSU and HDD

Trying to build my stepdad a new PC since his old P4 just aint cutting it anymore.

Looking for a perfectly working mobo cpu ram cooler combo to drop into a PC case. On-board video not needed, but if its good enough, that would be even better!

Also thinking to upgrade PSU and HDD. A cheap but quality 400w PSU, Seasonic Corsair Antec, etc... I'm also interested in a good used 300GB WD Caviar Blue SATA II. WD for sure anyways, somewhat new so its fast and reliable.
